## Completing the Feature Definition Group for a Point Feature

Use the options in the Feature definition group to define additional values for a Point feature.

### Feature Options

AA and AC Features

Note: The ID box will display the appropriate ID for the AA or AC feature. The graphic below shows an example for the AA feature.

### Descriptions

Note: For descriptions of the icons that appear in this group, see Using the Icons.

Item | Description
Desired point area | Note: When you hover your mouse over an option in this area, a screen tip about the option appears. Reference point area:

- Center boxes: These boxes display the X, Y, and Z coordinates of the point.

- Vector boxes: These boxes display the I, J, and K values of the point's vector for the measurement.

- RT boxes: Type the I, J, and K values of the point's RT (report vector) for the evaluation of the point.

- +Tol lists: Select the upper tolerances for the X, Y, Z, and RT dimension axes.

- -Tol lists: Select the lower tolerances for the X, Y, Z, and RT dimension axes.

- Output X-axis, Output Y-axis, Output Z-axis, and Output RT-axis check boxes: To print tolerances to the Edit Window and to reports (when PC-DMIS is set up to store information in a format to be viewed textually), select the check box for each tolerance you want to print. The check box for each axis that needs to be evaluated according to the option you select in the E-Rule list is automatically selected (and greyed out). You can change these check boxes only by selecting a different option in the E-Rule list.

- Comments boxes: Type comments in these boxes. The comments will appear in front of the dimensions in reports when PC-DMIS is set up to store information in a format to be viewed textually.

- E-Rule list: Select the E-Rule (evaluation rule), which defines the axis that will be tolerated. To view the description of an option, hover your mouse over the option. The option that you select becomes part of the ID in the ID box.

- T-Rule box: Use this box to save the current tolerances in a T-Rule (tolerance rule). This is useful for tolerances that are used often, such as -0.3 and 0.3. You can also recall the tolerances for an existing T-Rule and delete a T-Rule.

- To save the current tolerances in the +Tol and -Tol lists, type a name for the T-Rule in the T-Rule box, right-click in the box, and select Save:

The new T-Rule appears in the list.

- To recall the tolerances for an existing T-Rule, select the rule in the list.

- To delete a T-Rule, select the rule you want to delete, right-click, and select Delete.

- ID box: This box displays the ID of the point. The option that you select in the E-Rule list becomes part of the ID. The ID of the dimension appears underneath this box.
